7.6 EGTD – 7.6kW, 60 Hz Diesel Generator

Description

New Westerbeke 7.6 EGTD 7.6 kW 60 Hz Marine Diesel Generator For Sale

Compact, Low-Speed Power for Yachts and Professional Vessels

The Westerbeke 7.6 EGTD 7.6 kW 60 Hz Marine Diesel Generator is a compact, electronically governed generator developed for motor yachts, sailing yachts, cruising catamarans, liveaboard vessels, passenger boats, workboats, and other professional marine applications.

Rated at 7.6 kW, 60 Hz and 1800 RPM, the Westerbeke 7.6 EGTD combines a naturally aspirated three-cylinder diesel engine with a brushless four-pole alternator, freshwater cooling, electronic governing, a self-bleeding fuel system, remote controls, automatic safety shutdowns, and one-side service access.

The standard 7.6 EGTD-614 configuration supplies 120/240V single-phase electricity at approximately 63.3 amps at 120V or 31.6 amps at 240V. Westerbeke continues to list the 7.6 EGTD among its current-production traditional marine diesel generators.

Its electrical capacity may support compatible onboard systems such as:

• Battery chargers and inverter-chargers
• Marine refrigeration and freezers
• Freshwater and seawater pumps
• Navigation and communication electronics
• Cabin and deck lighting
• Electrical outlets
• Entertainment systems
• Selected galley appliances
• Appropriately sized air-conditioning systems
• Water makers and other auxiliary loads

Actual suitability depends on the vessel’s running demand, motor-starting current, simultaneous equipment use, distribution voltage, and required reserve capacity.

The Compact Westerbeke “Mini 8”

The 7.6 EGTD was designed for installations where the owner needs output close to 8 kW but does not have sufficient machinery-space clearance for a larger conventional generator.

Westerbeke uses a short alternator arrangement and tightly packaged engine components to reduce the generator’s overall footprint. The current product page lists the generator at approximately 28.4 inches long, 19 inches wide and 20.5 inches high, while retaining one-side access to many routine maintenance points. (Westerbeke)

The compact design makes the generator particularly attractive for:

• Yacht refits with restricted access
• Machinery spaces with limited headroom
• Catamarans with narrow generator compartments
• Replacement projects where a larger 8 kW set will not fit
• Installations requiring most service points on one side

Compact dimensions do not remove the need for sufficient ventilation, maintenance clearance, lifting access, and space to remove major components in the future.

Three-Cylinder Marine Diesel Engine

The Westerbeke 7.6 EGTD is powered by a naturally aspirated, three-cylinder, four-stroke diesel engine with approximately 58.09 cubic inches or 0.952 litres of displacement.

The engine operates at 1800 RPM in its 60 Hz configuration and develops approximately 12.4 hp at rated speed. Its published engine specifications include a 23:1 compression ratio, swirl-type combustion system, Bosch-type injection pump, throttle-type injectors, and a 12V glow-plug starting aid.

Engine specification	Published value
Number of cylinders	3
Cylinder arrangement	Vertical inline
Engine cycle	Four stroke
Aspiration	Naturally aspirated
Displacement	58.09 cu. in. / 0.952 L
Bore × stroke	2.99 × 2.76 in.
Compression ratio	23:1
Rated engine speed	1800 RPM
Engine output	Approximately 12.4 hp
Combustion system	Swirl type

The three-cylinder configuration provides smoother operation than many compact single-cylinder or twin-cylinder generators. Its low 1800 RPM speed also reduces mechanical operating frequency compared with high-speed 3600 RPM marine generator sets.

Potential advantages include:

• Smoother power delivery
• Reduced vibration
• Lower perceived engine noise
• Improved suitability for extended operation
• Reduced mechanical speed
• Practical routine maintenance

7.6 kW Electrical Output at 60 Hz

The Westerbeke 7.6 EGTD 7.6-614 is rated to produce 7.6 kW of electrical power at 60 Hz.

Electrical specification	Rating
Rated electrical output	7.6 kW
Voltage	120/240V
Rated current	63.3/31.6 amps
Frequency	60 Hz
Phase	Single phase
Number of wires	Four
Power factor	1.0
Operating speed	1800 RPM
Starting arrangement	Remote

These ratings are taken from Westerbeke’s official advanced specification sheet.

A professional marine electrical load calculation should be completed before selecting the generator. The assessment should consider:

• Continuous electrical demand
• Air-conditioning compressor startup
• Refrigeration compressor startup
• Pump and electric-motor starting current
• Battery-charger demand
• Simultaneous appliance operation
• Generator operating reserve
• Future electrical additions

Compressors and electric motors may draw significantly more current during startup than during normal operation. A generator may appear large enough when only the running loads are added together but still struggle when several high-demand systems start at the same time.

Electronic Governing for Stable Frequency

The 7.6 EGTD 7.6 uses an electronic engine governor to help maintain the correct 1800 RPM operating speed as electrical demand changes.

When a pump, compressor, charger, or other substantial load starts, the generator engine experiences an immediate increase in mechanical resistance. The electronic governor adjusts fuel delivery to limit the reduction in engine speed and maintain stable 60 Hz output.

This supports the reliable operation of compatible:

• Marine air-conditioning systems
• Refrigeration compressors
• Battery chargers
• Electric pumps
• Navigation electronics
• Communication equipment
• Lighting circuits
• Entertainment systems

Westerbeke includes electronic governing as standard on the 7.6 EGTD 7.6. The system improves transient-load response but cannot compensate for severe or continuous overloading.

Brushless Four-Pole Alternator

The 7.6 EGTD 7.6 uses a brushless four-pole marine alternator designed to produce 60 Hz electricity at 1800 RPM.

Its alternator construction incorporates:

• Brushless operation
• Four-pole electrical design
• Class H winding insulation
• Double vacuum epoxy-impregnated windings
• Marine-environment protection
• AC output circuit breaker
• Cooling airflow through the generator housing

Westerbeke states that the Class H insulation and epoxy-impregnation process provide increased protection against demanding marine conditions.

Brushless construction reduces routine servicing associated with carbon brushes, while the four-pole design allows the generator to operate at half the speed of a typical two-pole 60 Hz generator.

Reliable onboard electrical performance still depends on correct:

• AC cable sizing
• Circuit protection
• Grounding and bonding
• Shore-power transfer switching
• Load management
• Machinery-space ventilation
• Installation by qualified personnel

Freshwater Cooling with Marine Heat Exchanger

The Westerbeke 7.6 EGTD 7.6 uses a freshwater cooling system with a marine heat exchanger.

Engine coolant circulates through the cylinder block, cylinder head, and freshwater-cooled exhaust components. Raw water drawn from outside the vessel removes heat through the heat exchanger before being discharged through the water-injected exhaust system.

Published cooling features include:

• Closed freshwater coolant circuit
• Marine heat exchanger
• Coolant-recovery tank
• Gear-driven raw-water pump
• Freshwater-cooled exhaust arrangement
• 45-degree water-injected exhaust elbow
• One-inch raw-water connection

The published cooling-system capacity is approximately 4 US quarts or 3.78 litres.

Routine cooling-system maintenance should include inspection of:

• Engine coolant level and condition
• Raw-water seacock
• Seawater strainer
• Raw-water pump impeller
• Heat-exchanger passages
• Cooling hoses and clamps
• Exhaust-injection elbow
• Siphon-break arrangement
• Wet-exhaust hose
• Waterlift muffler

Restricted raw-water flow may cause high coolant or exhaust temperature and activate the generator’s protective shutdown system.

Self-Bleeding Diesel Fuel System

The 7.6 EGTD 7.6 incorporates a self-bleeding marine diesel fuel system designed to simplify operation after routine filter replacement or minor fuel-system servicing.

Published fuel-system features include:

• Primary and secondary fuel filtration
• Bosch-type fuel-injection pump
• Throttle-type injectors
• 12V electric fuel-transfer pump
• Fuel-supply and return connections
• Self-bleeding operation

Westerbeke specifies fuel piping between approximately ¼-inch and ⅜-inch internal diameter, depending on the installation.

A properly engineered fuel system should also include:

• A suitable marine fuel-water separator
• Accessible shutoff valves
• Correctly sized supply and return lines
• Marine-approved fuel hose
• Secure hose supports
• Protection from excessive heat
• Clean diesel fuel

Approximate Fuel Consumption

Westerbeke publishes the following approximate consumption figures for the 7.6 EGTD operating at 1800 RPM:

Generator load	Approximate fuel consumption
100% load	0.93 US gal/hr / 3.5 L/hr
75% load	0.67 US gal/hr / 2.5 L/hr
50% load	0.50 US gal/hr / 1.9 L/hr
25% load	0.36 US gal/hr / 1.4 L/hr

Actual fuel use may vary according to connected load, generator condition, fuel quality, machinery-space temperature, ventilation, installation, and maintenance.

Running the generator near a sensible working load is generally preferable to operating it for prolonged periods with little electrical demand. The vessel’s load-management strategy should be reviewed as part of the generator-selection process.

Remote Instrument Panel and Unit-Mounted Controls

The standard generator package includes a remote instrument panel with a 15-foot extension harness as well as a unit-mounted start-and-stop control.

This allows the generator to be controlled from a convenient location aboard the vessel while retaining local controls for commissioning, inspection, and service work.

Standard control features include:

• Remote instrument panel
• 15-foot extension harness
• Preheat control
• Start control
• Stop control
• Generator-mounted start and stop
• AC output circuit breaker
• Automatic safety shutdowns

Optional dual-station controls and additional remote-start arrangements are also listed by Westerbeke.

Automatic Safety Shutdowns

The Westerbeke 7.6 EGTD 7.6 monitors important engine and generator conditions and can shut down automatically when a potentially damaging fault is detected.

Published protection includes:

• Engine overspeed
• Engine underspeed
• Low starting-battery voltage
• Low lubricating-oil pressure
• High exhaust temperature
• High engine-coolant temperature

These protections help reduce the risk of severe damage, but they do not replace normal pre-start inspections or scheduled maintenance.

Operators should regularly inspect:

• Engine-oil level
• Coolant level
• Raw-water discharge
• Fuel supply
• Drive belt
• Hoses and clamps
• Electrical connections
• Exhaust components
• Machinery-space ventilation

50-Amp Battery-Charging Alternator

The 7.6 EGTD 7.6 includes a 50-amp, 12V charging alternator for maintaining the generator’s starting battery while the engine is operating.

The published electrical specification also lists a 12V solenoid-operated starting motor and approximately 190 cranking amps.

The generator starting battery should be:

• Correctly sized
• Properly secured
• Connected using marine-grade cables
• Protected with suitable switching and circuit protection
• Inspected for corrosion and loose terminals
• Maintained at an adequate state of charge

Quiet 1800 RPM Operation

The Westerbeke 7.6 EGTD 7.6 combines several design features intended to reduce noise and vibration:

• Low-speed 1800 RPM operation
• Three-cylinder diesel engine
• Tuned air-intake silencer
• Four-point vibration mounting
• Fail-safe rubber anti-vibration mounts
• Water-injected exhaust
• Compact alternator construction

Westerbeke positions the generator as a low-speed, quiet alternative for vessels where a full-sized 8 kW generator may be difficult to install.

Final onboard noise levels will also depend on:

• Generator foundation
• Machinery-space insulation
• Ventilation openings
• Exhaust-muffler selection
• Exhaust-hose routing
• Flexible connections
• Structural vibration transmission
• Optional Sound Guard installation

Full-Torque Power Take-Off Interface

The generator incorporates a full-torque power take-off interface.

With a correctly engineered electric clutch and hydraulic pump, the interface may be used to support compatible auxiliary systems such as:

• Bow or stern thrusters
• Hydraulic winches
• Compressors
• Hydraulic pumps
• Emergency “get-home” arrangements

The electric clutch, hydraulic pump, controls, and associated installation are customer-sourced and must be matched to the engine’s available output. Power used through the take-off reduces the power available for electrical generation, so the complete system must be professionally engineered.

One-Side Serviceability

One of the most useful features of the 7.6 EGTD 7.6 is its one-side service arrangement.

Routine service components are positioned to improve access in confined machinery spaces. Standard maintenance features include:

• Top and side oil-fill points
• Lubricating-oil drain hose
• Drip tray
• Full-flow spin-on oil filter
• Accessible fuel-system components
• Belt guard
• Coolant-recovery tank
• One-side maintenance access

This arrangement can simplify routine servicing, but adequate clearance must still be provided for filter removal, belt inspection, hose replacement, electrical service, and major repairs.

Optional Westerbeke Sound Guard SST

The 7.6 EGTD is compatible with an optional Westerbeke Sound Guard SST enclosure.

The enclosure uses a corrosion-resistant stainless-steel base and frame with powder-coated aluminium panels. All five panels can be removed to improve access for servicing and maintenance.

The relevant installation drawing shows approximate enclosure dimensions of:

Sound Guard measurement	Approximate dimension
Length	33.31 in. / 846 mm
Width	21.91 in. / 557 mm
Height	22.32 in. / 567 mm

The enclosure includes connection points for the raw-water system, siphon break, fuel lines, exhaust, battery cables, AC wiring, and generator grounding. Adequate exterior airflow and sufficient room to remove the panels must be maintained.
